Learning Objectives
  • Understand the acid-base theories of Arrhenius, Bronsted-Lowry, and Lewis
  • Identify strong acids and bases and calculate their pH’s
  • Calculate the pH of a weak acid or base
  • Calculate the concentration of a strong or weak acid or base from its pH
  • Calculate the pH and ion concentrations in a polyprotic acid
  • Predict the pH of a salt from its formula and then calculate the pH of the salt
  • Identify the components of a buffer and perform calculations involving the preparation of a buffer and the addition of strong acid or strong base to a buffer
  • Perform calculations involving strong acid-strong base titrations as well as weak acid-strong base and weak base-strong acid calculations
  • Be familiar with titration curves and selection of an acid-base indicator
  • Write balanced equations for the dissociation of a salt and its corresponding solubility product expression
  • Predict the relative solubilities of salts which dissolve to give the same number of ions from their Ksp values
  • Calculate the Ksp value from the solubility of a salt and also calculate the solubility of the salt in units of mol/L or g/L from the given Ksp value
  • Predict the effect of a common ion on the solubility of a salt and perform calculations
  • Perform calculations to predict if a precipitate will form when two solutions are mixed
  • Do problems involving selective precipitation
  • Use qualitative analysis to separate a mixture of ions
